Very good but I couldn't get the add to unity button to work. I can't find it in the Package Manager.

You can't use this out of box, you need to edit it for it to work and when it does it creates decent prototype icons. I generated a better script in ChatGPT in 5 minutes. Don't use this if you don't know how to fix code.

Free is best!

For a free asset it is ok. It functions as it should, but that's its limit. Very little options... I may suggest adding a few different camera angle options at the least.

Does not work.

works great wish it had an option to make a transparent background or change the color of it.

Nice tool but isn't modular enough for some purposes. Coding level is beginner

This might work for some basic Prefabs, but out of the 6 i tried only 1 was recognized as a 3d object. Def faster to just use photoshop and a screenshot. or maybe buy a paid asset that does this. Personally, this isn't worth the Download.

the icon will contain gray background, but it works!

Easy to use and does what it is supposed to do
